Kitanosho Castle

Kitanosho Castle (北ノ庄城, Kitanoshō-jō) was a hirashiro (castle located on flatland). Its remains are located in current-day Fukui, Fukui Prefecture, Japan. As the castle lasted merely eight years, few records survive about it. It is known, though that it was built by Shibata Katsuie in 1575. Also, it appears that the tenshu (keep) was nine stories high, making it the largest of the time.
